Lette/rs Patent No. 100,685, 1a-tell MarchS, 1870.

IMPRQVEMENT 1N MACHINE Fon BENDING FEnLons.

The Schedule referred to in these Lettere Patent and making part ox' thesame p To all whom tt may concern Be it known that I, DAVID A. SPRINKLE,of Leoti,

in the county of Iike, and in the Stateof Indiana,-

have invented certain new and useful Improvements in Press for BendingFelices or Hoops for Vehicles; and do hereby declare that thefollowingis afnll, clear, and exact description thereof', referencebeing had to the accompanying drawings and to the letters of referencemarked thereon,lmaking a part of this specitication.

The nature of my inventionconsists- 14`irst,'n an auxiliarylever hingedat its inner end to the main lever, and connected with it at its outer-end-4 by a chain.

-ISecond, in the manner of `changing the position of the main lever bymeans of areversible box, so as to.

accommodate the lever to the increased or diminished radius of theformer, as the movable former isor is not used.

In order to enable others skilled in the art towhich `my inventionappertainst-o make and use the same, I will norv proceed to describeits' construction and operation, referring to the annexed drawings, inwhich- Figure 1 lis a plan view of the machine, and

.11`igure2 isa vertical section of a portion ofthefralnc.V

A represents a frame of anyxsuitable dimensions and shape, although Iprefer to make the same in semicircular form.

On the upper side of the frame A is firmly secured the stationary circleor former B, which is provided across its face near the center with agroove, a, asseeu in fig 1.

.Around the circumference of the stationary former B, is placed amovable circle or former, C, which is near its ends provided with anotch or groove forming a` continuation of the groove I of thestationary former .at both ends.

` `One,*two, or more of these movable formers may be unto set my handthis 28th day of August, 1869.

used if desired. .p I

` On the stationary crcleB 'is pivoted a center-box, b, one end of whichextends fart-her beyond the pivot than the other end.

On this box is placed a lever, D, having at a snitable point on itsunder side a pulley or friction-roller,` d. To the inner end of thelevel' D is pivoted another lever E, which also is provided with a.friction-roller, d, and connected with the former lever D by a chain, e.A portion of the frame A is slotted, and in this slot is placed anadjustable upright, f, to which an iron strap, h, is secured.

fi represents the felloe or hoop to be bent-l 'lhe hoop i is insertedand held between the end of the movable circle G and the `iron straph,and the levers D and E, so arranged that the friction-moliere d d willbear on the outer side of' the iron strap; then', by turning the leversfrom` right lto left, the hoop is bent aroundthe circle'G, the' strap hkeeping the hoop from breaking. When thus bent, a lath, or other stripof Wood is insertedin the groove a, and nailed to the ends of the hoopor felloe, and cau'then be taken off'.

When it is,` desired to bend the yfelice around the stationary circle B,the levers are taken oif the cent-erbox la, saidbox turned around, thelevers put on again, and the upright f moved closerin toward the circle.

Having thus fully described my invention,

What I claim as new, and desire to secure bvLetters Patent, is

1. In combination with thc main level', the auxiliary lever E hinged andconnected to the mainlever-as described, and both provided with rollersd d, subst-an tially as and for the purposes herein set forth.

2. The reversible box b pivot-ed to the stationary former B, andconstructed substantially i'n the manuel' and for the purposes hereinset forth.

3. The arrangement of the frame A, stationary former B, movable formerO, groove a, levers D E, rollers d d, box b, upright f, and strap l1.,'all constructed as described and operating substantially as and for thepurposes herein set forth.

In .testimony that I claim the foregoing, I have here- Witnesses DAVIDA. SPRINKLE.
